I'm only close, when I'm trading well, I nearly quit last March took a contract and been much much busier than I expected, expected just support work, so free to trade near full time, epic fail.
5 years is close enough, I wouldn't of expected 10, some years I've barely made 2 trades.
Combine, could get you there much faster, keeps your sim trading straight if nothing else, as long as it's not costing you too much!
